The purpose of the study was to develop and standardize a new self-report scale to measure the well-being of Indian adolescents. One of the significant approaches of the study was to adopt a new mathematical method—Rough set theory—to derive a shorter form of the scale instead of using the frequently used method of principal component analysis, exploratory factor analysis, and confirmatory factor analysis in scale construction process. The findings gave rise to a 117-item scale, named as Indian Scale of Adolescent Well-being (ISAW) and its shorter form, known as ISAW-SF in the form of a super reduction consisting of 15 items. The psychometric properties of the ISAW and ISAW-SF were established on a sample of 3271 adolescents selected from three States of India. Developing the norm, the ISAW-SF was recommended to be used as a screening, diagnostic, or research instrument. The 15-item ISAW-SF is the first of its kind to measure the significant 12 dimensions of well-being. Its usability may be extended to other cultures after cross-cultural adaptation and validation.
